V twin taking ages to fire up - any thoughts on this?

Back in the day I had a 2013 RT, and on 2 occasions (both after trailering bike) the bike wouldn't start. It would crank over fine but not start. After around 10 secs of cranking it timed out and this took around 3 "cycles" before the bike finally, reluctantly, spluttered into life. i never pursued the issue and have since moved on, but a friend with 2015 RSS rang and she has the same problem. My thought was a non-return valve in the fuel line, maybe letting fuel drain back to the tank. She hadn't trailered her bike either. Does anyone have a thought on this? It is totally intermittent.

Try T.W.O (Throttle Wide Open). Has been helpful, & follow up with some tlc fresh ethanol free 93 octane or better. Maybe take a peak at throttle bodies & replace fuel/air filters. General service items inspection.

Fuel. Wide open throttle is generally for a FLOOD CLEAR scenario. A fuel pressure test will provide an indication of what is wrong.
